Abstract: A primary online system infers interests for its users based on interest information in a secondary online system. Users that have user profiles in both the primary online system and the secondary online system are identified, and those associated with a target interest in the secondary online system are selected as part of a training group of that is used to generate an interest inference model that associates information in the training group's user profiles in the primary online system with the target interest. The interest inference model is applied to an input group of users in the primary online system to identify a seed group of users for whom the target interest can be inferred. The primary online system can then target content related to the target interest to an expanded group of users generated based on the seed group.
